Abstract

A dispenser for liquid germicide includes a container for germicide and an outlet, a metering device for metering a given amount of germicide to be dispensed from the outlet, a spout communicating with the metering device for dispensing metered germicide, and a timing arrangement coupled to the metering device for timed control of the frequency of dispensing the metered amount of germicide.

Claims

1. A dispenser for liquid germicide, comprising a container for germicide having an outlet, a metering device for metering a given amount of germicide to be dispensed fluidly communicating with said outlet, a spout fluidly communicating with said metering device for dispensing metered germicide, and timing means coupled to said metering device for timingly controlling the frequency of dispensing said metered amount of germicide;

said timing means including a delay device in engagement with said dispenser for inhibiting the dispensing of said given amount of germicide until elapse of a given time determined by said delay device;

said delay device including a timing cylinder containing a viscous liquid, a timing piston axially movable in said cylinder, and friction means for allowing said piston to move slowly in one direction and fast in the opposite direction, and release linkage coupling said timing piston to said metering means for timed releasing of said metering means.

2. Dispenser according to claim 1 wherein said metering device include a metering cylinder, a metering piston slidably disposed in said metering cylinder, an intake valve in said metering cylinder fluidly communicating with said outlet, and an outlet valve fluidly communicating with said spout.

3. A dispenser according to claim 1, wherein said metering device includes an inlet for fluid-tight engagement with said outlet and a spout for ejecting said germicide.

4. Dispenser according to claim 3, including an atomizer coupled to said spout for atomizing said germicide at said spout.

5. A dispenser according to claim 1, including a housing for enclosing said container, said metering device and said timing means.

6. A dispenser according to claim 5, wherein said container is a rigid cannister, including a pressure agent disposed in said cannister for exerting pressure on said liquid germicide.

7. A dispenser according to claim 5, including a window in said housing for view the germicide level in said container.

8. A dispenser according to claim 5, wherein said container is flexibly yieldable, and including a spring-biased baffle disposed internally of said housing, in engagement with said container for exerting a given pressure on said liquid germicide.

9. A dispenser according to claim 8, including a foaming agent disposed in said container for foaming said germicide as it is expelled through said spout.

10. Dispenser according to claim 8 including a seal in said container outlet, a metering inlet attached to said metering device for fluidly communicating with said outlet, and piercing means disposed in said metering inlet for piercing said seal upon attachment of said container to said metering inlet.
